OSPAR's Quality Status Report 2023 Friday Ocean Findings Issue 24
Assessments of Marine Bird Abundance, Marine Bird Breeding Productivity and Trends in New Records of Non-Indigenous Species (NIS) Introduced by Human Activities are now available on our assessment portal.

These assessments contribute to our 2023 Quality Status Report (QSR) which, when viewed together, build a picture of the overall condition of the marine environment of the North-East Atlantic and progress towards achieving our vision of a clean, healthy and biologically diverse North-East Atlantic Ocean, which is productive, used sustainably and resilient to climate change and ocean acidification. The results will also be used by OSPAR Contracting Parties to inform policy decisions.

We hope you enjoy these Indicator Assessments. Please do contact us with any comments at communications@ospar.org
Marine Bird Abundance

Marine birds are in poor status and declining in most of the OSPAR Maritime Area. This mainly refers to birds feeding at the water surface, diving to the seafloor or foraging in shallow water / on mudflats, whereas birds feeding in the water column and herbivores are usually doing better.

Marine Bird Breeding Productivity

Across Arctic Waters, Greater North Sea and Celtic Seas (OSPAR Regions I, II and III), for most species marine bird breeding productivity was so poor that future population size declines are likely. Breeding productivity was above threshold for the two species assessed in Bay of Biscay and Iberian coast (Region IV).

Trends in New Records of Non-Indigenous Species (NIS) Introduced by Human Activities

Non-indigenous species (NIS) continue to arrive in high numbers to OSPAR Regions, with potential negative effects on ecosystems. The rate of introduction, mostly crustaceans and macroalgae, is slightly decreasing in Greater North Sea (Region II), Celtic Seas (Region III), and Bay of Biscay and Iberian Coast (Region IV), although lag time in report might explain this trend. Current monitoring shortfalls disable assessment of NIS dispersal and impact.
